FINALIZING THE INSTALLATION
FLAME APPEARANCE:
Flame appearance is affected by several factors including altitude, venting configuration and fuel quality. Although the
venturi setting has been factory set, adjustments may be necessary for optimal performance and visual aesthetics.
When fireplace is first lit, the flames will be blue. The flames will gradually turn yellowish-orange during the first 15 min-
utes of operation. If the flames remain blue or the flames become dark orange with evidence of sooting (black tips), the
burner tube venturi may need to be adjusted.
WARNING: BURNER TUBE ADJUSTABLE VENTURI POSITIONING
SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.
